you really think "we will have a good laugh over it". So I also complained
with the source ISP. That being ovh.net, I don't expect a lot of response.

Searching a bit for 'snapfish spam' finds I'm not the only one receiving
junk from them. Or it is their affiliate program causing spam.

Update 2012-12-09:
A new day, a new spam from an ovh customer, this time for be2.nl (dating site)
with affiliate codes embedded. I guess affiliate programs need to work really
hard to weed out spammers.
